Like you, I also have my iPhone that when I feel like listening to stream line music I just plug into my Bose Soundock, Bose Soundlink mini or Bose Audio Adapter which is just fine and sounds great, various radio stations that I can tune into from other states, different music, etc., etc.
I have a small collection of various tuners that I have acquired over time (and still do). Personally for me, since as a kid, I remember having a kids radio kit that I assembled and would listen to radio stations with small headphones! I've always been drawn to radio's leading specifically to tuners. I just don't like any type of tuner. For me the tuner has to have specific details, features, unusual distinctive looks and quality.
The following is a list of tuners that I have in my small collection (and still looking and adding):
Lafayette LT-D10
Magnum Dynalab FT-101A
Akai AT-550
Akai AT-580
SAE 8000 (have two of these)
SAE TWO T14 (given to me by fellow AK'er Lawman)
Harman Kardon Citation Fourteen
Harman Kardon Citation Fifteen
Toshiba ST335MkII (have two of these)
Kenwood KT-5000
Pioneer TX-5100
Overall, I guess it all comes down to an individuals love of not only listening to the radio station but on what type of tuner that you enjoy listening on. Not that its important but the fun of its features, etc. of it.
